A load P is supported by a structure consisting of rigid bar ABC, two identical solid bronze [E = 14100 ksi] rods, and a solid steel [E = 30100 ksi] rod, as shown. The bronze rods (1) each have a diameter of 0.8 in. and they are symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod (2) has a diameter of 0.49 in. Assume L1=31 in and L2=61 in. If all bars are unstressed before the load P is applied, determine the normal
